IMPROVEMENT lN CORSET-SPRINGS.

Specification forming part of Letters Patent N 0. 123,938, datedFebruary 20, 1872.

companyin g drawing forming part of this specification, in whichdrawing- Figure 1 represents a face view of my invention. Fig. 2 is alongitudinal section of the same in the plane a: 00, Fig. 1.

$in1ilar letters indicate corresponding parts. his invention relates tothat class of corsetsprings in which is employed a mainspring providedwith an auxiliary leaf and the invention consists in securing thesecondary leaf upon the mainspring and by means of projecting teats orlugs located on each side of the central fastening clasp, the ends ofthe said secondary leaf being loosely confined between the end clasps soas to accommodate itself to the motions of the main leaf.

In the drawing, the letter A designates a corset-spring, which iscomposed of a main- The secondary or auxiliary leaf is slipped looselythrough the fastenin g-clasps 0, which are provided with recesses toreceive the same; and it is held in position by two projections, d (I,raised thereon, one on either side of the central clasp 0.

By these means the secondary leaf is prevented from being displaced,and, at the same time, its ends are left free to accommodate itself tothe motions of the mainspring, and the mainspring retains its fullstrength, there being no perforations for rivets. The mainspring andauxiliary leaf may be made of any desired material; but, by preferencethe mainspring is made of highly-tempered steel, while the auxiliaryleaf is made of some tough metal, such as hard rolled brass, which has acertain degree of elasticity, but which is not liable to break.

By combining the two leaves a b so that the leaf 1) will have its freeends arranged between clasps a spring is produced which combinessuperior elasticity, and which will permit the said secondary spring toaccommodate itself to the movement of the Inainspring.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- As a new article of manufacture, thecorsetspring, constructed as described, consisting of the mainspring a,auxiliary leaf b, projections d d, and clasps c c, all combined andoperating as herein shown and set forth.

This specification signed this 8th day of J anuary, 1872.
